TO ALL WHOM IT MAY CONCERN:

Be it known that I, IMILLIAM C. ABBILof Petroleum Centre, Vennngocounty, Pennsylvanie, have invented a new and improved Pipe-livrench;and I do hereby declare thnttl1c following iss. full, clear, and exactdescription the1cof,which will enable others skilled in the art to mnkeund use the same, reference being had to the accompanying drawings,forming p art of this specification, in which- Figure 1 is a side viewof my improved pipe-wrench, and Figure 2 an edge View. Similar lettersof reference indicate corresponding parts.

This invention relates to en improved construction of' n wrench forcoupling and uncoupling gus and other pipe or tubing, bolts, orroundscrews of any kind, and consists in connecting two jointed segmentaljaws to the end of a. single-hand lever, in such a. manner that they maybe opened to admit between their concave serrated edges pipes ofdifferent sizes, which they will clasp firmly around their sides, andhold rigidly, when a. hooked point on the short arm of the hand-levershall bea-r upon a.,nib or projection on the side of one end of' one ofthe segmental jews, as hereinafter more particularly described. v

A is a hand-lever, to'one end of which is pivoted at a. one end ofsegmental jaw, B, on the other end of which jaw is pivoted 'anothersegmental jaw, C, both of which jews are provided with teethorcorrugated edges on their concavesides facing euch other. The jaws areso shaped in compound lines 4of curvature tha-t they will hug closelyupon `a. large surfuce of the sides of a. pipe placed between them, andthus secure a. firm hold upon it, which will ellow it to be turnedagninsta.l strong resistance without slipping on or defacing the outsideofthe pipe.`- On the extremity of the jaw C a. riib or lug, '6, isformed et the side, upon which hooked pointe, on the short-arm of thelever A, catches to close the jaw upon the pipe, by lifting the lever onthe fulcrum pivot a of the jaw B. Either one or two lugs may be used.

' Having. thus described my invention, what I claim as new, and desireto secure by Letters Patent, isl The segmental jews C, in combinationwith the lever A, constructed and'operating substantially as and for thepurpose described. v
